Abstract

PROBLEM TO BE SOLVED: To display a focus component by reproducing it without hiding the focus component even though design change is performed.SOLUTION: A first priority determination value for determining a first priority order for displaying each component at a first time point about each of components at the first time point during designing is calculated. A second priority determination value for determining a second priority order for displaying each component at a second time point about each of the components at the second time point after the first time point is calculated. When the first priority order determined by the first priority determination value is different from the second priority order determined by the second priority determination value, one viewing point and one of one or more viewing point candidates are selected as new viewing points on the basis of a third priority determination value corresponding to the second priority determination value calculated by replacing the one viewing point with each viewing point candidate about each of one or more viewing point candidates different from the one viewing point, and a display part reproduces and displays a state where the component is seen from the selected new viewing point at the first time point.SELECTED DRAWING: Figure 23

  Hereinafter, embodiments of a design support program, an information processing apparatus, and a design support method disclosed in the present application will be described in detail with reference to the drawings. However, the embodiment described below is merely an example, and there is no intention to exclude application of various modifications and techniques not explicitly described in the embodiment. That is, the present embodiment can be implemented with various modifications without departing from the spirit of the present embodiment. Each figure is not intended to include only the components shown in the figure, and may include other functions. And each embodiment can be suitably combined in the range which does not contradict a processing content.

[1] Related Technology As described above, in the related technology, when reproducing the display state of the defective part, it is not considered that the current state is changed from the state at the time of recording the defective part. In other words, with the progress of product design after recording the defect location, parts that were visible at the time of recording the defect location may be hidden and hidden by newly added parts or parts whose arrangement has been changed. . Therefore, in the viewpoint position and display state recorded for the defective part, the part that is originally intended to be displayed, that is, the target part cannot be displayed, and the designer or the like may not be able to confirm the target part.

  For example, as shown in FIG. 1, in the related technology, the same part is specified or a newly added part is specified based on assembly model configuration information (part ID) before and after the design change. . FIG. 1 is a diagram illustrating an example of a correspondence relationship between an assembly model configuration before design change and an assembly model configuration after design change.

  In the example shown in FIG. 1, it is determined that parts having the same part ID “A” are the same parts before and after the design change. Thus, after the same part is specified before and after the design change, the display / non-display state of the specified part is reproduced. Hereinafter, the component with the component ID “A” is referred to as a component A.

  Further, it is determined that the part E that does not exist before the design change but exists after the design change is a newly added part. However, since the state regarding display / non-display is not set for the new additional component, the additional component blocks the line of sight. For example, when the state of FIG. 2A (before the design change) is changed to the state of FIG. 2B, that is, the state where the part E is added, the line of sight from the viewpoint before the design change is blocked by the part E. The part B becomes invisible from the viewpoint before the design change.

  Further, even if the state of FIG. 2A (before the design change) is changed to the state of FIG. 2C, that is, the state where the part D is moved, the line of sight from the viewpoint before the design change is blocked by the part D. The target component B becomes invisible from the viewpoint before the design change. 2A to 2C are diagrams illustrating an example in which the target component that was visible before the design change is no longer visible after the design change on the display screen.

  As described above, the display / non-display state of each part cannot be reproduced well only by specifying the same part before and after the design change.

  In addition, the viewpoint position including information on "what you are looking at and where you are confirming" in order to reproduce and reuse the display state of the troubled part during the confirmation of many parts (faulty part etc.) It is extremely troublesome to distinguish and save (input a viewpoint name or the like). For this reason, many technologies having a function of saving the viewpoint position have been proposed but are not utilized.

[2] Outline of the present embodiment Next, an outline of the present embodiment will be described. In view of the state of the related art as described above, in this embodiment, various problems are solved and various effects are obtained by realizing various functions as follows.

  In the information processing apparatus (computer) of the present embodiment, the target part (target part) is estimated based on the frequently used viewpoint position and display state, and the target part is moved or changed in shape, or the target part is moved to the vicinity. It is possible to automatically reproduce the viewpoint position and display state in accordance with changes such as the addition of components (see FIGS. 32 and 33).

  Here, in order to estimate the point of interest, the viewpoint position and the display state may be determined by combining display states around the point of interest based on the viewpoint (shortest distance) and the line of sight (projection distance). For parts movement, part shape change, part addition, etc. that occur during the design of the design target model, determine the priority order of the parts to be displayed based on the shortest distance and projection distance described later You may respond with. Then, by changing the viewpoint position based on the recorded measurement point (measurement point) of each component, the display state may be reproduced from a viewpoint close to the display state (recording state) at the time of recording (FIG. 32, FIG. 32). 33). Note that the measurement point (measurement point) of each component corresponds to a point (vertex) on each component when the shortest distance between the viewpoint and each component is calculated.

  At this time, without displaying the display state by a special means, the display state of the part frequently referred to is automatically reproduced and displayed as the display state of the target part based on the usual screen operation state by the designer or the like. (See FIGS. 32 and 33). Thereby, the viewpoint movement to the point of interest and the reproduction of the display state can be easily performed, and the reproduction display that follows the design progress of the design target model can be performed.

  In addition, the information processing apparatus according to the present embodiment is an apparatus that is suitable for use in reproducing past design examples of a pointed point structure, for example, display of a position where a defect has occurred (display state of a defect position). For this reason, in the information processing apparatus of the present embodiment, even if the parts that make up the product, which are handled as a virtual three-dimensional assembly model, change with the progress of design, the failure part is reproduced and displayed following the change. The following functions (11) to (14) are provided for performing (see FIGS. 12 to 27).

(11) Reproduction information recording function (see FIGS. 5, 8 to 11, and 13 to 19)
The function (11) automatically records defect information 22 and viewpoint reproduction information 23, which will be described later, when a defect occurs or when a display from a certain viewpoint satisfies a predetermined condition (for example, continues for a predetermined time or more). As will be described later, the information includes the shortest distance between the viewpoint and each part, the projection distance between the screen center of the viewpoint image and each part, the viewpoint image, and notes / Dimension display location, etc. are included. The viewpoint image is an image (display state) that is seen when viewed from the viewpoint in a predetermined line-of-sight direction, and is also referred to as a visual field image.

(12) Display state reproduction function (see FIGS. 5 and 21 to 27)
The function (12) reproduces the display of the part that matches the part at the time of recording by the function (11). In addition, the function (12) was displayed at the time of recording along with the movement even if the part does not match the part at the time of recording by the function (11) or the part at the time of recording by the function (11). For parts that hide other parts, display priority is determined based on the shortest distance and projection distance during recording. Further, the function (11) records the note or dimension based on the viewpoint and display state at the time of creation when the note or dimension is created, and the function (12) records the recorded note or dimension at present. Reproduced display according to the state.

  On the other hand, the function (12) changes the viewpoint position based on the difference (offset described later) between the measurement point of each component and the current measurement point of each component at the time of recording by the function (11). At this time, the function (12) acquires one or more offset viewpoints as viewpoint candidates based on the difference, and records at the time of recording based on a priority determination value (priority order) described later or a feature amount similarity described later. One of the viewpoint to the point of interest and one or more viewpoint candidates is selected as a new viewpoint. In other words, the function (12) compares the priority determination values and viewpoint images for each viewpoint, and uses a viewpoint with a low priority determination value (that is, a priority) or a viewpoint with a high similarity as a new viewpoint for the point of interest. Use. When comparing the viewpoint images, the viewpoint images may be compared, or the degree of similarity of the feature amounts of the viewpoint images obtained by machine learning may be compared.

(13) Automatic viewpoint recording function (see Figs. 5, 32, and 33)
The function (13) automatically records the reproduction information at the viewpoint and the viewpoint image at that time when the viewpoint is not moved or the display state is not changed for several seconds (predetermined time) after the viewpoint is moved. Then, the function (13) groups viewpoints that are physically close to the point of interest among the recorded viewpoints. In the same manner as the function (12), the function (13) selects one viewpoint (corresponding to a new viewpoint in the function (12)) from a plurality of viewpoints belonging to the same group as a representative point of the viewpoint. Here, the point of interest is the intersection of the line of sight from the viewpoint and the part surface (the surface of the part of interest that is the point of interest). As the same group, a group to which the most viewpoints belong may be selected.

(14) Viewpoint confirmation function (see FIGS. 5, 6, 28 to 31, 34, and 35)
The function (14) displays a reproduction mark that associates the point of interest with the viewpoint position to the point of interest on an output unit (display unit) described later, and a reproduction mark from an input unit (such as a mouse) described later. The display / non-display of the part is reproduced by a hover operation or the like, and the viewpoint image is displayed. The function (14) switches the display state on the display unit to the display state from the viewpoint with respect to the point of interest associated with the reproduction mark by selecting the reproduction mark by a click operation or the like. Further, the function (14) selects a reproduction mark (projection viewpoint) that is close in distance by projecting the reproduction mark onto the containing sphere and operating an arrow key or the like. Then, the function (14) moves the viewpoint of the viewpoint image to be displayed to the viewpoint associated with the selected reproduction mark, and reproduces the display state from the moved viewpoint on the display unit. Thereby, viewpoint movement can be performed easily.

  During the design, the state of the point of interest changes due to a shape change or layout change, and the state of the point of interest also changes when confirming a similar portion in another model product. A part of interest may be covered with a part with such a change. At this time, according to the information processing apparatus of this embodiment, by determining the priority order of the components to be displayed based on the shortest distance and the projection distance at the time of recording, the point of interest is tracked on the display unit following the change. It can be reproduced so that it can be seen. In this way, even if the design is changed, the target part can be reproduced and displayed without hiding it.

  Further, according to the information processing apparatus of the present embodiment, when the point of interest moves, the measurement point of the movement destination is compared with the measurement point of the movement source, and the viewpoint is moved to a point closer to the viewpoint at the time of recording. It is possible to reproduce and display a portion related to the point of interest.

  Furthermore, according to the information processing apparatus of the present embodiment, the viewing location and the display state are automatically recorded from the normal usage situation, and the frequently used viewpoint and the display state are displayed as display recommendation candidates on the display unit. It can also be displayed. Further, by performing a hover operation on the reproduction mark from the input unit, the viewpoint image associated with the reproduction mark can be simply displayed / reduced. Thereby, the viewpoint image and the display state can be confirmed before the screen (viewpoint) is switched (see FIG. 31).

  As described above, according to the information processing apparatus of the present embodiment, by using the various functions (11) to (14) described above, it is possible to easily switch the viewpoint and the display state with respect to the point of interest, and the product to be designed Various confirmation processes performed on can be shortened.

The vertex ID of the measurement point specifies the vertex on the part corresponding to the measurement point.

[3-2] Functions Performed by the Processing Unit and the Output Unit of the Present Embodiment Next, various functions performed by the processing unit 30 and the output unit 40 of the present embodiment, that is, the reproduction information recording unit 31, the display state reproduction unit 32, The functions of the new viewpoint reproduction unit 33, the point of interest viewpoint estimation unit 34, the mark display control unit 35, the point of interest viewpoint grouping unit 36, the viewpoint movement unit 37, the reproduction display unit 41, and the reproduction mark display unit 42 will be described.

  The reproduction information recording unit 31 regards one of a plurality of parts included in the three-dimensional assembly model as a target location (target component; fault location) when a fault occurs during design, and the fault information 22 related to the target location. Alternatively, the viewpoint reproduction information 23 (see FIGS. 8 to 11) may be acquired and recorded in the storage unit 20. The acquisition / recording operation of the various information 22 and 23 related to the defect location by the reproduction information recording unit 31 when the defect occurs will be described later with reference to FIGS.

  In addition, the reproduction information recording unit 31 may automatically record the viewpoint reproduction information 23 when the display from a certain viewpoint satisfies a predetermined condition (for example, continued for a predetermined time or longer) by an operation of a designer or the like. The acquisition / recording operation of the viewpoint reproduction information 23 by the reproduction information recording unit 31 when the predetermined condition is satisfied will be described later with reference to FIGS. 32 and 33.

  The display state reproduction unit 32 is based on the defect information 22 and the viewpoint reproduction information 23 recorded in the storage unit 20, and the display state focusing on the defect point at the time of the defect occurrence in the 3D assembly model that has been designed, or the designer The display state of the point of interest from a viewpoint that is frequently used is reproduced and displayed on the output unit 40. At this time, the reproduction display unit 41 is a function realized by controlling the display state of the output unit 40 by the display state reproduction unit 32, and the display unit 40 displays and reproduces the display state of the point of interest in the output unit (display unit) 40. indicate.

  The new viewpoint reproduction unit 33 has a difference (offset) between the measurement point of each part at the time of recording the information 22 and 23 and the measurement point of each current part (part in a state where the design has advanced). The viewpoint position is changed based on the difference. At this time, the new viewpoint reproduction unit 33 acquires one or more offset viewpoints as viewpoint candidates (new viewpoint candidates) based on the difference.

  The point-of-interest viewpoint estimation unit 34 selects one of a viewpoint to the point of interest at the time of recording and one or more viewpoint candidates based on a priority determination value (priority order) described later or a similarity of a feature amount described later. Select as a new perspective. That is, the point-of-interest viewpoint estimation unit 34 compares the priority determination value and the viewpoint image (similarity of the feature amount of the viewpoint image by machine learning) for each viewpoint, and the viewpoint with a low priority determination value (that is, a higher priority). Or a viewpoint with high similarity is employ | adopted as a new viewpoint with respect to an attention location. Specific operations of the new viewpoint reproduction unit 33 and the point of interest viewpoint estimation unit 34 described above will be described later with reference to FIGS.

  The functions as the new viewpoint reproduction unit 33 and the point of interest viewpoint estimation unit 34 described above cause the design support program of this embodiment to cause the computer 1 (processing unit 30) to execute the following processes (21) to (24). (See FIG. 23).

  The process (21) is based on the first shortest distance between the one viewpoint and each part and the first projection distance for each part (reproduction source model part) at the time of occurrence of a failure in design (first time point). Then, a first priority determination value that determines the first priority for displaying each component when a failure occurs is calculated (see FIG. 24). Here, the first projection distance is a projection distance between each component and the first screen center of the first display screen that displays a state where the target component at the time of the malfunction is viewed from the one viewpoint.

  The process (22) is performed for each of the parts (reproduction destination model parts) at the present time (second time point) after the occurrence of the failure, to the second shortest distance between the one viewpoint and each part and the second projection distance. Based on this, a second priority determination value for determining the second priority order for displaying each component at the present time is calculated (see FIG. 25). Here, the second projection distance is a projection distance between each component and the second screen center of the second display screen that displays the current state of the component viewed from the one viewpoint.

  In the process (23), when the first priority order and the second priority order are different from each other, one or more viewpoint candidates different from the one viewpoint (see FIGS. 26 and 27), the one viewpoint is set as each viewpoint candidate. Based on the third priority determination value corresponding to the second priority determination value calculated by the replacement, one of the one viewpoint and the one or more viewpoint candidates is selected as a new viewpoint. Here, the first priority and the second priority are determined by the first priority determination value and the second priority determination value, respectively.

  In the process (24), the output unit (display unit) 40 reproduces and displays a state where the part (target part) at the time of occurrence of the defect is viewed from the new viewpoint selected in the process (23).

  At this time, the processing unit 30 calculates a smaller first priority determination value for a component that is closer to the center of the first screen among components at the time of occurrence of the failure, and determines a higher first priority for a component that has a smaller first priority determination value. . In addition, the processing unit 30 calculates a second priority determination value smaller for a component closer to the center of the second screen among components at the present time, and determines a second priority higher for a component having a smaller second priority determination value. More specifically, a value obtained by multiplying the value of the first shortest distance by the square value of the first projection distance is used as the first priority determination value, and the value of the second shortest distance is used as the second priority determination value. A value obtained by multiplying the square value of the second projection distance is used.

  Further, the processing unit 30 includes a total value of the second priority determination values of the components calculated for the one viewpoint, and a total value of the third priority determination values of the components calculated for each of the one or more viewpoint candidates. Of these, the viewpoint having the smallest total value is selected as the new viewpoint.

  Here, a case will be described in which the first time point is a time when a failure occurs and the second time point is the current time. The one viewpoint is a viewpoint at the time of occurrence of a malfunction, and the one or more viewpoint candidates are obtained by moving the one viewpoint with reference to the position of each component having a different first priority and second priority. It is assumed that there are one or more offset viewpoints.

  The point-of-interest viewpoint grouping unit 36 is used when automatic setting of the point-of-interest in the present embodiment, which will be described later with reference to FIG. 32, that is, when realizing the above-described viewpoint automatic recording function (13). In the function (13), as described above, when the viewpoint is not moved or the display state is not changed for a few seconds (predetermined time) after the viewpoint is moved, the reproduction information and the viewpoint image at that time are automatically recorded. The

  The point-of-interest viewpoint grouping unit 36 groups viewpoints that are physically close to the point of interest for a plurality of recorded viewpoints during automatic setting of the point-of-interest. In the present embodiment, one viewpoint (corresponding to a new viewpoint) is selected from a plurality of viewpoints belonging to the same group by using the functions as the new viewpoint reproduction section 33 and the point of interest viewpoint estimation section 34, that is, the function (12). Is selected as the representative point of the viewpoint.

  The mark display control unit 35 changes the display state of the output unit 40 so that a reproduction mark described later with reference to FIGS. 28 to 31 and 34 is displayed on the reproduction mark display unit 42 of the output unit (display unit) 40. Control. That is, the reproduction mark display unit 42 is a function realized by the mark display control unit 35 controlling the display state of the output unit 40.

  The mark display control unit 35 displays a reproduction mark connecting the viewpoint and the point of interest on the reproduction mark display unit 42 (see FIG. 29), and also displays a display when a defect occurs by hovering the reproduction mark with a cursor. The state may be previewed (see FIG. 31). Further, the mark display control unit 35 may display a viewpoint image, a model name of a point of interest, or the like in the vicinity of the reproduction mark during preview.

  The mark display control unit 35 may perform a reproduction mark selection operation using a mouse or the like to switch the display state to a state viewed from the viewpoint defined by the reproduction mark and reproduce and display it.

  The mark display control unit 35 reproduces a reproduction mark close to the current viewpoint based on the angle difference between the current line of sight connecting the current viewpoint and the point of interest and the line of sight connecting the viewpoint of the reproduction mark and the point of interest. Control may be performed so that the reproduction mark display unit 42 displays the mark separately from the mark (see FIG. 34). At this time, for example, the mark display control unit 35 may perform control so as to display only the reproduction mark that is close to the line-of-sight direction from the current viewpoint position among the plurality of reproduction marks displayed on the reproduction mark display unit 42. Good.

  The viewpoint moving unit 37 normalizes the line-of-sight direction (viewpoint) of the reproduction mark by projecting it onto the inclusion sphere of the three-dimensional assembly model, and responds to instructions from the input unit 10 such as keyboard arrow key operations and mouse scroll operations. Then, the next projection viewpoint that is close to the distance on the containing sphere from the current viewpoint is selected. That is, the viewpoint moving unit 37 sequentially selects reproduction marks that are close in distance from among a plurality of reproduction marks projected on the inclusion sphere in response to an instruction from the input unit 10. Thereby, the viewpoint moving unit 37 moves the viewpoint of the viewpoint image to be displayed to the viewpoint associated with the selected reproduction mark (see FIG. 35), and reproduces the display state from the moved viewpoint on the display unit 40. To do.

[4] Operation of Information Processing Apparatus According to this Embodiment Next, the operation of the information processing apparatus 1 according to this embodiment configured as described above will be described with reference to FIGS.

[4-1] Procedure for Recording and Reproducing Fault Location First, according to the flowchart shown in FIG. 12 (steps S1 to S7), the procedure for recording and reproducing the fault location (operation of the processing unit 30) in this embodiment will be described. . In the example illustrated in FIG. 12, the defect information 22 and the viewpoint reproduction information 23 relating to the defect location (pointed location) where the failure has occurred are recorded, and the output unit 40 shows a state in which the three-dimensional assembly model is updated according to the design progress. It may be reflected in the display state.

  As shown in FIG. 12, in the present embodiment, when a problem occurs during the design of the product to be designed, the location where the problem has occurred (failure location) is captured as the focus location (target component), and the output unit 40. Is displayed. As described above, the defect information 22 and the viewpoint reproduction information 23 (see FIGS. 8 to 11) including the viewpoint and display state when displaying the defect portion are acquired by the reproduction information recording unit 31 and the input unit 10, and are stored in the storage unit. 20 (step S1). The process of step S1 will be described later with reference to FIGS.

  After recording and saving information 22, 23, etc. relating to the defective part in the storage unit 20 in step S 1, when the designer or the like refers to and confirms the defective part recorded in the storage unit 20, the design progress model, that is, the reproduction destination model is read. It is. Then, the defect to be reproduced, that is, the reproduction source model is selected from the defect information 22, and the parts of the reproduction destination model and the reproduction source model are matched (step S2). The process of step S2 will be described later with reference to FIG.

  Thereafter, the display state of the selected defective portion is reproduced and displayed based on the viewpoint reproduction information 23 in the state in which the model that has been designed is displayed, that is, in the reproduction destination model, according to the determination result by the matching (step S3). The process of step S3 will be described later with reference to FIGS.

  Then, in a state in which the display state of the defective part is reproduced in step S3, the display screen displays the shortest distance L1 (see FIG. 17) between the viewpoint and each component and the state where each component is viewed from the viewpoint. It is determined whether or not there is a difference in the projection distance L2 (see FIG. 19) from the center of the screen (step S4).

  When there is no difference between the shortest distance L1 and the projection distance L2, that is, when the shortest distance L1 and the projection distance L2 match (NO route in step S4), the shape of each part between the reproduction source model and the reproduction destination model This corresponds to the case where there is no change in the arrangement position or the like, and the reproduction display in step S3 is maintained as it is (step S7).

  On the other hand, when there is a difference between the shortest distance L1 and the projection distance L2, that is, when the shortest distance L1 and the projection distance L2 do not match (YES route in step S4), when there is a change in the shape or arrangement position of each part. Correspondingly, the processing of steps S5 to S7 is executed.

  In step S5, when there is an offset between the measurement point of each component at the time of recording the defect location and the measurement point of the component in the state where the design has progressed, the function as the new viewpoint reproduction unit 33 is based on the offset, One or more offset viewpoints are acquired as new viewpoint candidates.

  In step S6, the function as the point-of-interest viewpoint estimation unit 34 uses the priority determination value (priority order) described later or the similarity of the feature amount described later, and the viewpoint to the point of interest at the time of recording and one or more viewpoint candidates. Is selected as the new viewpoint. That is, for each viewpoint, priority determination values and viewpoint images (similarities of feature quantities of viewpoint images by machine learning) are compared, and viewpoints with low priority determination values, that is, viewpoints with high priority, or viewpoints with high similarity, Adopted as a new viewpoint for the point of interest.

  In step S7, the function as the display state reproduction unit 32 outputs the state in which the display state focusing on the defective part at the time of the failure in the designed 3D assembly model is changed to the new viewpoint that adopts the viewpoint. This is reproduced and displayed on the part (display part) 40.

  Note that the processing in steps S5 and S6, that is, the specific operations of the new viewpoint reproduction unit 33 and the point-of-interest viewpoint estimation unit 34 will be described later with reference to FIGS.

[4-2] Procedure for Recording Fault Location Next, referring to FIG. 14 to FIG. 19 according to the flowchart shown in FIG. 13 (steps S11 to S19), the process of step S1 shown in FIG. The recording procedure will be described. Here, for example, regarding the display state of the 3D assembly model during creation of indication items including defect information etc., in addition to the viewpoint position, the line-of-sight direction, the enlargement ratio, and the display state of the part with respect to the origin of the target 3D assembly model, The viewing distance from the viewpoint to each visible component surface in the display area (view field area) and the component position (two-dimensional coordinates on the image) in the display area may be recorded.

  As shown in FIG. 13, first, when a problem occurs during the design of a product to be designed, a three-dimensional assembly model at the time of the problem as shown in FIG. The display state is input (step S11). FIG. 14 is a diagram illustrating an example of a three-dimensional assembly model when a failure occurs.

  At this time, as shown in FIG. 8, the content of the defect as the defect information 22 is input along with the operation of the input unit 10 by the designer or the like. Then, the contents of the defect are recorded in the storage unit 20 in association with the defect ID that identifies the defect and the viewpoint reproduction information ID that identifies the viewpoint reproduction information 23 regarding the defect (step S12).

  Further, when a problem occurs, the reproduction information recording unit 31 acquires visual field information 231 (see FIG. 10) included in the viewpoint reproduction information 23 and records it in the storage unit 20 (step S13). The visual field information 231 includes viewpoint posture information acquired from the display state at the time of occurrence of the malfunction. As viewpoint information, the viewpoint position (see FIG. 15), the rotation angle, the viewing angle, and the line-of-sight direction (see FIG. 15) are based on the initial position of the viewpoint (the origin (0, 0, 0) of the global coordinate system). Arrow reference). FIG. 15 is a diagram for explaining the visual field information 231.

  Further, the display / non-display state of each component as shown in FIG. 16 is acquired by the reproduction information recording unit 31 and recorded in the storage unit 20 (step S14). Information regarding the display / non-display state is included in the viewpoint reproduction information 23. By recording the component ID for identifying the component in the non-display state as the non-display component ID (see component ID “C” in FIG. 9), the component with the non-display component ID is displayed on the screen as shown in FIG. Do not show. On the other hand, components with component IDs other than the non-display component ID are displayed on the screen as shown in FIG. FIG. 16 is a diagram for explaining display / non-display of model parts.

  Then, as shown in FIG. 17, the shortest distance (corresponding to the first shortest distance) L1 from the viewpoint coordinates (xc, yc, zc) indicating the viewpoint position at the time of the failure to each component is calculated. A point (vertex; coordinates (xp, yp, zp)) on each part when the shortest distance L1 is calculated is acquired as a measurement point of each part. That is, the shortest distance L1 corresponds to the distance between the viewpoint coordinates (xc, yc, zc) and the measurement point coordinates (xp, yp, zp). The shortest distance L1 at the time of occurrence of the failure acquired as described above is recorded in the storage unit 20 as measurement information 232 as shown in FIG. 11 (step S15). The shortest distance L1 may be acquired by the processing unit 30 and recorded by the reproduction information recording unit 31. FIG. 17 is a diagram illustrating the shortest distance (corresponding to the first shortest distance) L1 between the viewpoint and each component.

  Next, information indicating whether each component that can exist in the visual field area from the viewpoint at the time of the failure is visible, that is, information indicating whether or not each component can be confirmed in the visual field area is the reproduction information recording unit 31. And is recorded as visible / invisible information (see FIG. 11) (step S16). In the example shown in FIG. 18, the component B that is displayed in the visual field area is recorded as visible in the measurement information 232, and the component C that is not displayed in the visual field area is recorded as invisible in the measurement information 232. FIG. 18 is a diagram for explaining visible / invisible in the visual field area.

  Thereafter, it is determined whether or not each component is visible in the visual field area (step S17). When the target part is invisible (NO route of step S17), the processing unit 30 (reproduction information recording unit 31) proceeds to the process of step S19.

  When the target component is visible (YES route in step S17), the screen center of the display screen (corresponding to the first screen center of the first display screen) that displays the state viewed from the viewpoint at the time of the failure and the target component A projection distance (corresponding to the first projection distance) L2 is calculated. That is, as shown in FIG. 19, the screen center (uc, vc) of the viewpoint image (the display screen) and the vertex coordinates on the target component when the shortest distance L1 is acquired (that is, the measurement point coordinates (xp, The length of the line segment connecting the coordinates (up, vp) of the points projected onto the viewpoint image is calculated as the projection distance L2. As shown in FIG. 11, the calculated projection distance L2 is associated with the part ID of the target part together with the measurement point coordinates (xp, yp, zp), the surface ID and the vertex ID on the model part to which the measurement point belongs. And recorded (step S18). The projection distance L2, the measurement point coordinates (xp, yp, zp), the surface ID, and the vertex ID may be acquired by the processing unit 30 and recorded by the reproduction information recording unit 31. FIG. 19 is a diagram illustrating a projection distance (corresponding to a first projection distance) L2 between the screen center and each component.

  In step S19, the reproduction information recording unit 31 determines whether information about all the components in the visual field area has been acquired. When information about all the components in the visual field area is acquired (YES route in step S19), the processing unit 30 (reproduction information recording unit 31) ends the recording of the defective part. On the other hand, when the information about all the parts in the visual field area has not been acquired (NO route of step S19), the processing unit 30 (reproduction information recording unit 31) returns to the processing of step S14, Information acquisition processing is continued for parts for which information has not been acquired.

[4-3] Procedure for reading design progress model, selecting defect to reproduce, and matching procedure Next, in accordance with the flowchart shown in FIG. 20 (steps S21 to S23), the process of step S2 shown in FIG. The procedure for loading a model, selecting a defect to be reproduced, and matching will be described.

  When the designer or the like refers to and confirms the defect location recorded in the storage unit 20, in the process of step S2 shown in FIG. 12, first, the design progression model input from the input unit 10 by the designer or the other system, that is, The reproduction destination model is read (step S21). The reproduction destination model is a three-dimensional assembly model as shown in FIG. The reproduction destination three-dimensional assembly model read in this way is displayed on the output unit 40.

  Then, in accordance with the operation of the input unit 10 by the designer or the like, the defect ID to be reproduced, that is, the reproduction source model is selected from the defect information 22 shown in FIG. 8 (step S22).

  Thereafter, the parts are matched with the model information of the selected defect information and the information of the three-dimensional assembly model that is the reproduction destination (step S23). That is, the parts of the reproduction source model and the reproduction destination model are matched. Thereby, it is determined whether or not there is a part corresponding to the reproduction source model and the reproduction destination model (the presence or absence of matching data).

  The matching can be performed by automatically determining or manually determining the presence or absence of a component with a matching component ID using a unique component ID. Further, the determination result by matching is used in the processing of steps S32 and S33 in FIG.

[4-4] Procedure for Reproducing Display State Next, the process of step S3 shown in FIG. 12, that is, the procedure for reproducing the display state will be described with reference to the flowchart (steps S31 to S34) shown in FIG. Here, in the process of step S3 shown in FIG. 12, a model (reproduction destination model) whose design has progressed after the occurrence of a defect based on the line-of-sight reproduction information 23 recorded by the processing unit 30 (display state reproduction unit 32). The display state at the time of malfunction is reproduced as follows.

  First, initial reproduction is performed (step S31). In the initial reproduction, using the selected defect ID, visual field information 231 (see FIG. 10) corresponding to the defect ID is extracted from the viewpoint reproduction information 23 (see FIG. 9). Then, based on the extracted visual field information 231, the position and orientation of the viewpoint are set to the state at the time of occurrence of the malfunction. That is, the viewpoint position is arranged at the viewpoint position (Xc, Yc, Zc) of the extracted visual field information 231 with the global coordinates as the origin. Further, the viewpoint posture (the direction of the line of sight) is arranged at a position rotated by the rotation angle (Xθ, Yθ, Zθ) of the extracted visual field information 231 with respect to the three axes X, Y, and Z, respectively.

  In the initial reproduction, components existing in the visual field area defined by the viewpoint of the extracted visual field information 231 are specified. At this time, all the parts displayed even in a part in the visual field area (display area) are specified, and the part ID of the specified part is acquired as the reproduction destination model ID.

  Next, for all reproduction destination model parts specified in step S31, whether or not the reproduction source model part ID corresponding to the reproduction destination model part ID can be acquired based on the determination result by the matching in step S23 of FIG. To be judged. When the reproduction source model part ID corresponding to the reproduction destination model part ID can be acquired, that is, when there is matching data, the reproduction destination model part having the matching data is displayed according to the display / non-display state of the corresponding reproduction source model part. Is reflected (step S32).

  On the other hand, when the reproduction source model part ID corresponding to the reproduction destination model part ID cannot be acquired, that is, when there is no matching data and the part is added, the reproduction destination model part without the matching data has the shortest distance in the display area. It is determined whether or not the measurement point used for the calculation covers the existing surface. When the reproduction destination model part without matching data does not cover the measurement point, the current display state is maintained. If the reproduction destination model part without matching data covers the measurement point, the reproduction destination model part without matching data is changed to a non-display state (step S33).

  Thereafter, the cover parts processing as described below is executed in accordance with the display priority order of the reproduction source model parts (step S34). If the low priority part covers the high priority part in the currently reproduced display state by the cover part process, the low priority part is changed to the non-display state.

  Next, according to the flowchart (steps S41 to S46) shown in FIG. 22, the process of step S34 shown in FIG.

  First, the display priority order of the reproduction source model part is determined (step S41). Here, based on the shortest distance L1 and the projection distance L2 of each reproduction source model part, a priority determination value (determined as the first priority determination value) for determining the priority order (corresponding to the first priority order) for displaying each reproduction source model part. Equivalent) is calculated. In this embodiment, the priority determination value is a value L1 × L2 × L2 obtained by multiplying the value of the shortest distance by the square value of the projection distance. The priority determination value becomes smaller as the component is closer to the center of the screen, in other words, as the component has a shorter projection distance. In this embodiment, the display priority is determined higher for a component closer to the center of the screen, that is, a component having a lower priority determination value.

  For example, as shown in FIG. 24, when 1000 is calculated as the priority determination value for part A and 2250 is calculated as the priority determination value for part B, the priority order of component A is determined to be higher than the priority order of component B. Is done. In the example shown in FIG. 24, the priorities of the parts A and B are determined as “1” and “2”, respectively. FIG. 24 is a diagram illustrating an example of the first priority determination value and the first priority order of the reproduction source model part.

  The process of step S41 is repeatedly executed until the priority order is determined for all reproduction source model parts (from the NO route of step S42 to step S41). When the priority order is determined for all the reproduction source model parts (YES route of step S42), the covering check is performed in the order of lower priority order (step S43).

  In the covering check, it is determined whether or not the target reproduction source model part is covered by a part with a high priority in the display area in the order of low priority, that is, in the order of high priority determination value. At this time, the covering check is the same as the measurement point of the reproduction source model part (see FIG. 11), or whether the measurement point of the reproduction destination model part is visible or the measurement point belongs. This is done by determining whether the surface is visible. This determination may be made only for the higher-priority parts, and in this embodiment, for example, it is assumed that the higher-priority parts are used.

  As a result of the covering check, when a low priority part covers a high priority part, that is, when the measurement point is invisible (YES route in step S44), the target reproduction source model part is not The display state is changed (step S45). Thereafter, the processes in steps S43 to S45 are repeatedly executed until the covering check is completed for all reproduction source model parts (from the NO route in step S46 to step S43). When the covering check is completed for all the reproduction source model parts (YES route of step S46), the covering check is finished. As a result of the covering check, if a component with a low priority is not covered with a component with a high priority, that is, if the measurement point is visible (NO route of step S44), the process proceeds to step S46. To do.

[4-5] New Viewpoint Candidate Acquisition and New Viewpoint Selection Next, in accordance with the flowchart shown in FIG. 23 (steps S51 to S56), the processing in steps S5 and S6 shown in FIG. That is, a procedure for acquiring a new viewpoint candidate and selecting a new viewpoint will be described. The process described here is performed when it is determined that there is a difference between the shortest distance L1 and the projection distance L2 in the process of step S4 shown in FIG. It is executed when there is a change. The processing is executed by the processing unit 30 (the display state reproduction unit 32, the new viewpoint reproduction unit 33, and the target point viewpoint estimation unit 34).

  First, the priority determination value (corresponding to the first priority determination value) and the priority order (corresponding to the first priority determination value) for the reproduction source model part are acquired (step S51). Further, for the same viewpoint as the viewpoint for the reproduction source model part, the priority determination value (corresponding to the second priority determination value) and the priority order (corresponding to the second priority determination value) for the reproduction destination model part are acquired ( Step S52). In addition, since the process of step S51 is a process similar to step S41 mentioned above, step S51 may be replaced with step S41.

  In step S51, as described above, based on the first shortest distance L1 and the first projection distance L2 of each reproduction source model part, a first priority determination value for determining a first priority order for displaying each reproduction source model part is calculated. Is done. In the present embodiment, the first priority determination value is a value L1 × L2 × L2 obtained by multiplying the value of the first shortest distance by the square value of the first projection distance. The first priority determination value becomes smaller as the component is closer to the center of the first screen, in other words, as the component has a shorter first projection distance. In the present embodiment, the display priority is determined to be higher for a component closer to the center of the first screen, that is, a component having a lower priority determination value. As described above with reference to FIG. 24, in the example shown in FIG. 24, the first priorities of the parts A and B are determined as “1” and “2”, respectively.

  In step S52, based on the second shortest distance L1 and the second projection distance L2 of each reproduction destination model part, a second priority determination value for determining a second priority order for displaying each reproduction destination model part is calculated. In the present embodiment, like the first priority determination value described above, the second priority determination value is set to a value L1 × L2 × L2 obtained by multiplying the value of the second shortest distance by the square value of the second projection distance. The second priority determination value becomes smaller as the component is closer to the center of the second screen, in other words, as the component has a smaller second projection distance. In the present embodiment, the display priority is determined to be higher for a component that is closer to the center of the second screen, that is, a component with a lower priority determination value.

  For example, as shown in FIG. 25, when 1573 is calculated as the priority determination value of component A and 175 is calculated as the priority determination value of component B, the priority order of component B is determined to be higher than the priority order of component A. Is done. In the example shown in FIG. 25, the second priorities of the parts A and B are determined as “2” and “1”, respectively, and are reversed from the priorities of the reproduction source model parts A and B shown in FIG. Yes. FIG. 25 is a diagram illustrating an example of the second priority determination value and the second priority order of the reproduction destination model part.

  As described above, when the first priority order of the reproduction source model part and the second priority order of the reproduction target model part are determined for the same viewpoint, do these first priority order and second priority order differ? It is determined whether or not (step S53). When the first priority and the second priority match (NO route of step S53), there is no significant change between the reproduction source model parts and the reproduction destination model parts for the parts A and B having higher priorities. The process proceeds to step S7 in FIG.

  On the other hand, when the first priority and the second priority are different (YES route in step S53), there is a significant change between the reproduction source model parts and the reproduction destination model parts for the parts A and B with higher priority. Judge that there was. In this case, it is considered that the state relating to the parts A and B changes the original state (display state of the reproduction source model part) and makes it difficult to see the target part (target part). Therefore, a new viewpoint is selected from a plurality of (4 in the present embodiment) viewpoint candidates in order to change the viewpoint position so that the target component can be easily seen (steps S54 to S56).

  At this time, between the measurement point (reproduction source measurement point position) of each reproduction source model part A, B and the measurement point (reproduction destination measurement point position) after the design progress of each reproduction destination model part A, B Assume that an offset as shown in FIG. FIG. 26 is a diagram illustrating an example of offset values between the reproduction source model part and the reproduction destination model part. In the example shown in FIG. 26, an offset of (2, 0, 0) is generated for the part A and an offset of (-1, 0, 0) is generated for the part B with reference to the measurement point of the reproduction source. Further, the priority order of the top two parts A and B is changed between the reproduction source and the reproduction destination. Therefore, as shown in FIG. 27, the reproduction viewpoint (original viewpoint), the offset viewpoint based on the part A, the offset viewpoint based on the part B, and the midpoint viewpoint of the offset (offset viewpoint based on the part A and the part) Four of the B reference offset viewpoints are acquired as viewpoint candidates (step S54). FIG. 27 is a diagram illustrating an example of the position of a new viewpoint candidate.

  Then, the priority determination value (corresponding to the third priority determination value) and priority when each viewpoint candidate is employed are calculated and determined in the same manner as in FIG. 25 (step S55). Thereafter, for each viewpoint candidate, a total value of two priority determination values calculated for the top two components A and B (1573 + 1175 = 1748 in the example shown in FIG. 25) is calculated, and among the four viewpoint candidates, The viewpoint candidate with the smallest total value is selected as a new viewpoint (step S56).

  In the above-described embodiment, one new viewpoint is selected from a plurality of viewpoint candidates based on the total priority determination value. However, the present invention is not limited to this, and the similarity of the feature amounts of these images obtained by comparing the reproduction source image with the viewpoint candidate images viewed from each viewpoint candidate is added to the total priority determination value. In consideration, a viewpoint candidate may be selected as a new viewpoint.

  In this way, in the present embodiment, a viewpoint with a high priority or a viewpoint with a high degree of similarity of image feature values is adopted as a new viewpoint for the point of interest. Then, in the three-dimensional assembly model for which the design has progressed, the output state (display unit) 40 is reproduced and displayed in a state where the display state focusing on the defective part at the time of the defect is changed to the new viewpoint adopted ( Step S7 in FIG.

[4-6] Various displays including reproduction marks Next, various displays including reproduction marks displayed by the mark display control unit 35 and the reproduction mark display unit 42 of the present embodiment with reference to FIGS. 28 to 31. explain.

  In general, as shown in FIG. 28, the display state of the three-dimensional assembly model is defined by the viewpoint position, the line-of-sight direction, the point of interest, etc. in the space where the three-dimensional assembly model exists. The viewpoint position, the line-of-sight direction, the point of interest, and the like are included in the visual field information 231 (see FIG. 10). The point of interest is an intersection of the line of sight and the part, and corresponds to a defect point, a defect location, a focus location, a focus point, and the like. FIG. 28 is a diagram showing the viewpoint / line of sight / point of interest.

  At this time, the reproduction mark display unit 42 of the output unit 40 of the present embodiment displays visual field information 231 including the position of the viewpoint, the direction of the line of sight, and the position of the point of interest, as shown in FIG. And can be displayed as a reproduction mark on a three-dimensional assembly model. FIG. 29 is a diagram showing a display example of reproduction marks corresponding to the viewpoint / line of sight / point of interest shown in FIG.

  As shown in FIG. 30, when all the parts of the three-dimensional assembly model are in the display state (all display states), the point of interest (the part of interest) cannot be seen from the viewpoint of the reproduction mark. Even in such a case, in the present embodiment, as shown in FIG. 30, the reproduction mark may be displayed on the output unit 40 so as to indicate the line of sight from the viewpoint through the component in the display state. Good. FIG. 30 is a diagram illustrating an example of a full display state and a display example of reproduction marks.

  Furthermore, in the present embodiment, as shown in FIG. 31, when the reproduction mark is hovered with the cursor by the operation of the input unit 10 by the designer or the like with the three-dimensional assembly model or the reproduction mark displayed, the reproduction mark is displayed. The display state at the corresponding viewpoint / line of sight (display state when a defect occurs) is previewed. At this time, a preview screen (display image after switching the viewpoint) may be displayed in the vicinity of the reproduction mark, or a display image, a model name of a point of interest, or the like may be displayed. In such a display state, a reproduction mark selection operation is performed by a mouse operation or the like, so that the display state on the output unit 40 is a state viewed from the viewpoint defined by the reproduction mark (display image after switching the viewpoint in FIG. ). FIG. 31 is a diagram illustrating an example of a display state during preview and a display example of reproduction marks.

[4-7] Automatic Point of Interest Setting Next, the procedure of automatic setting of the point of interest in the present embodiment will be described according to the flowchart (steps S61 to S65) shown in FIG.

  As described above, the reproduction information recording unit 31 of the present embodiment automatically displays the viewpoint reproduction information 23 when the display from a certain viewpoint satisfies a predetermined condition (for example, continued for a predetermined time or more) by an operation of a designer or the like. It may be recorded. Below, the acquisition / recording operation | movement of the viewpoint reproduction information 23 by the reproduction information recording part 31 when predetermined conditions are satisfy | filled is demonstrated. At this time, based on the viewpoint reproduction information 23 recorded in the storage unit 20, the display state reproduction unit 32 reproduces and displays the display state of the point of interest at the viewpoint used frequently by designers and the like on the output unit 40. To do.

  As shown in FIG. 32, in this embodiment, for example, when the viewpoint is not moved or the display state is not changed for several seconds (predetermined time) after the viewpoint is moved, the viewpoint reproduction information 23 (FIGS. 11) and the viewpoint image at that time are acquired and automatically recorded by the reproduction information recording unit 31 (step S61). The processing in step S61 will be described later with reference to FIG.

  In the present embodiment, at the time of automatic setting of the point of interest, the point-of-view viewpoint grouping unit 36 groups viewpoints that are physically close to the point of interest among the plurality of recorded viewpoints (step S62).

  Furthermore, in the present embodiment, a single viewpoint (new viewpoint) is selected from a plurality of viewpoints belonging to the same group by using the same function as the function (12), that is, the functions as the new viewpoint reproduction unit 33 and the target location viewpoint estimation unit 34. Is selected as the representative point of the viewpoint (steps S63 and S64).

  In step S63, a plurality of viewpoints belonging to the same group are captured as viewpoint candidates.

  In step S64, the priority determination value and the priority order when each viewpoint candidate is adopted are calculated and determined in the same manner as in FIG. Thereafter, for each viewpoint candidate, for example, a total value of two priority determination values calculated for the top two components A and B is calculated, and among the plurality of viewpoint candidates, a viewpoint candidate having the smallest total value is selected. Selected as a new viewpoint (representative point).

  Then, a reproduction mark for the selected new viewpoint is created and displayed on the output unit 40 (step S65). When a plurality of reproduction marks are displayed in step S65, a display method described later with reference to FIG. 34 may be used.

  In this way, according to the viewpoint automatic recording function (13) of the present embodiment, a change between a viewpoint that satisfies a predetermined condition and its display state is recorded, and a representative point of the viewpoint that is frequently used is output. Displayed by the reproduction mark in the section 40. The designer or the like can reproduce and display the display state of the point of interest from the viewpoint frequently used by the designer or the like by operating the reproduction mark on the output unit 40.

  Here, according to the flowchart shown in FIG. 33 (steps S71 to S79), the process in step S61 shown in FIG. 32, that is, the viewpoint recording procedure will be described.

  As shown in FIG. 33, it is first determined whether or not the viewpoint or display state has changed within a few seconds (predetermined time) after the designer or the like has moved the viewpoint or changed the display state (step S71). Step S72). If the viewpoint or display state changes within a predetermined time (YES route of step S72), the process returns to step S71, and the next viewpoint movement or display state change is performed.

  On the other hand, when the viewpoint or the display state does not change within a predetermined time (NO route of step S72), the processing (viewpoint recording) of steps S73 to S79 is performed based on the viewpoint after movement. Here, the processing of steps S73 to S79 shown in FIG. 33 is the same as the processing of steps S13 to S19 shown in FIG.

[4-8] Reproduction Mark Display Control According to Line of Sight Next, an example of reproduction mark display control according to the line of sight according to the present embodiment will be described with reference to FIG. The display control may be applied when the mark display control unit 35 displays a plurality of reproduction marks in step S65 shown in FIG.

  At this time, in the display control, among the plurality of reproduction marks displayed on the reproduction mark display unit 42 (output unit 40), only the reproduction mark that is close to the line of sight from the current viewpoint position is displayed as shown in FIG. Is done.

[4-9] Movement of viewpoint according to distance between viewpoints projected on inclusion sphere Next, with reference to FIG. 35, the distance between viewpoints projected on the inclusion sphere in the present embodiment by the viewpoint moving unit 37, with reference to FIG. An example of viewpoint movement according to the will be described.

  As shown in FIG. 35, when a plurality of (three in the figure) reproduction marks are displayed at various positions, the viewpoint moving unit 37 sets the line-of-sight direction (viewpoint) of the reproduction marks of the three-dimensional assembly model. Project onto the containing sphere and normalize. Then, in response to an instruction from the input unit 10 such as an arrow key operation on the keyboard or a scroll operation on the mouse, the viewpoint moving unit 37 changes the viewpoint from the current viewpoint to the next viewpoint with a short distance on the containing sphere ( Projection viewpoint) Move.

  That is, in accordance with an instruction from the input unit 10, a projection viewpoint that is close in distance (that is, a reproduction mark corresponding to the projection viewpoint) is sequentially selected from a plurality of projection viewpoints projected on the inclusion sphere. Thereby, the viewpoint of the viewpoint image to be displayed is moved to the viewpoint defined by the selected reproduction mark, and the display state from the moved viewpoint is reproduced on the display unit 40. Thereby, viewpoint movement can be performed easily.

  The viewpoint movement using the inclusion sphere described above is used to make it easier for a designer or the like to select a registered viewpoint. By projecting and using the viewpoint on the containing sphere, it is possible to select either the viewpoint of viewing a nearby part or the viewpoint of viewing a distant part based on the projected viewpoint projected on the same containing sphere. In other words, by placing importance on the selection of the line-of-sight direction rather than the viewpoint position, the viewpoint position for zooming in on a nearby part can be changed to the viewpoint position for zooming out a wide area including a distant part, or vice versa. It can be moved accurately.
